Here's an informed piece that helped change our own thinking in several areas, including quantitative easing (QE). So much so that coverage of the same material here would be tantamount to plagiarism, and, as these writers get paid in part by the 1,000 hits, potentially unfair to the author as well. We'll just say that there's been a QE before in American history, and, like so far this year, theirs worked rather well for equity investors (by suspending the stock market cycle for a while), plus, with a little luck in the timing, their Feds managed to pull off an end game that made it all go away without complete catastrophe (though the author's not saying that part will happen again). It's a long read, but well worth your perusal. Onliest thing out there that isn't pure unadulterated seat-of-your-pants economic guesswork too.
As ever, keep your eye on the income stream and not on the capital when navigating through a financial storm.
